Gonef: Vanilla Planets on Nauvis

A TIMSABA-focused alternative progression for players who want to keep modded
planets but skip the four standard Space Age planets.

What it changes

• Hides Vulcanus, Fulgora, Gleba, and Aquilo.
• Keeps the installed modded planets and reconnects routes that originally
  passed through the hidden vanilla planets.
• Adds Nauvis recipes for calcite, tungsten ore, holmium ore, Yumako,
  Jellynut, pentapod eggs, ammoniacal solution, fluorine, and lithium brine.
• Makes the corresponding planet-specific machines and production chains
  usable on Nauvis.
• Removes Agricultural science packs from every technology cost, including
  technologies added by other mods.
• Hides the Agricultural science pack item and recipe.
• Replaces the old Agricultural science technology with Gleba
  biochemistry, a normal laboratory research using science up to Space
  science. This preserves discovery contributions used by modded planets such
  as Muluna without requiring Bioflux or Agricultural science packs.
• Bioflux remains available as an optional intermediate for recipes that still
  use it.

Compatibility

Built and tested with Factorio 2.0.77 and TIMSABA 1.13.1. The complete target
mod pack was tested both by creating a new map and by loading an existing save.

This mod is intentionally specific to the TIMSABA progression and declares
TIMSABA as a required dependency. Do not combine it with other mods that remove
or merge Space Age planets.

Existing saves

The mod does not delete existing surfaces. It hides the four vanilla planet
destinations, disables the Agricultural science recipe for all forces, and
preserves existing items for save safety.
